-LRB- CNN -RRB- -- Army Sgt. Kimberly Walker survived two tours of duty in Iraq -- only to be killed back home , allegedly by her boyfriend .

Now , eight months later , her family is mourning again because they ca n't keep two SpongeBob Squarepants memorials at her gravesite .

To say Walker loved the cartoon character may be an understatement .

`` Every year , my sister had a SpongeBob birthday party , '' Walker 's twin sister Kara said . `` Everything she had was SpongeBob . ''

Even her curtains and bathroom were decked out with the underwater fry cook 's image , her mother told CNN affiliate WLWT .

`` The funeral home actually bought the pillow of SpongeBob and we asked if they could put it in her casket , '' Deborah Walker said .

So the family decided to spend $ 26,000 on two massive SpongeBob monuments at Walker 's gravesite -- one in an Army uniform for Walker , and another in a Navy uniform to honor Kara , an IT specialist for the Navy .

Each of the monuments stands more than 6 feet tall and weighs 7,000 pounds .

Before the family ordered the SpongeBob memorials , it got the go-ahead from a cemetery representative , Deborah Walker said .

`` They came and said , ` Yeah , we can go ahead and do SpongeBob . ' She gave us a statement , we signed a contract , and then they started the design , '' the mother told WLWT .

The stone SpongeBobs finally arrived on October 10 . But less than a day later , Spring Grove Cemetery in Cincinnati said it was going to remove the statues .

`` The family chose a design with the guidance of a Spring Grove employee who unfortunately made an error in judgment , '' the cemetery 's president told CNN . `` The monument does not fit within Spring Grove Cemetery guidelines , was not approved by senior management and can not remain here . ''

Walker 's family is devastated .

`` It was just heartbreaking , '' Deborah Walker said . `` I just felt we were just trying to honor her wishes . ''

The family is going to meet with officials from the cemetery on Tuesday . Spring Grove said it is working with the Walkers to design a solution at the cemetery 's expense `` that will properly memorialize Kimberly . ''
